2023年7月17日 · Constrictive pericarditis, right ventricular failure (commonly due to infarction), and restrictive cardiomyopathy are conditions that frequently produce a positive hepatojugular reflux. Left ventricular failure also produces this sign, but usually when the PCWP is …

Hepatojugular reflux (HJR) is one of the clinical signs of volume overload, easily obtainable at bedside. The HJR is a simple, reliable, but neglected physical exam sign useful for diagnosing and managing HF.

2023年7月24日 · Hepatojugular reflux (HJR) is a physical finding observed during the clinical examination of the cardiovascular system. This comprehensive article aims to provide a thorough understanding of hepatojugular reflux, including its definition, causes, significance, evaluation, and clinical implications.

Hepatojugular reflux is the distension of the neck veins precipitated by the maneuver of firm pressure over the liver. It is seen in tricuspid regurgitation, heart failure due to other non-valvular causes, and other conditions including constrictive pericarditis, cardia tamponade, and inferior vena cava obstruction.

Hepatojugular reflux is a cardiac physical examination with a long history of use in heart failure diagnosis across many clinical settings. However, the development of new diagnostic methods has thrown the clinical role of hepatojugular reflux into question.

Hepatojugular reflux (HJR) is one of the clinical signs of volume overload, easily obtainable at bedside. The HJR is a simple, reliable, but neglected physical exam sign useful for diagnosing and managing HF.

In the absence of left heart failure, a positive abdominojugular reflux sign should prompt consideration of impaired right ventricular preload, a decrease in right ventricular compliance, a decrease in right ventricular systolic function or an elevation in right ventricular afterload.

What Causes Hepatojugular Reflux? Research has shown that a positive hepatojugular reflux, or when blood in the neck veins increases due to pressure on the abdomen, can be linked to a number of heart conditions.

Positive Result: A positive result is variously defined as either a sustained rise in the JVP of at least 4cm or more [2] or a fall of 4 cm or more [1] after the examiner releases pressure. The AJR has a reported sensitivity of 24% [4] to 72% [1] and a specificity of 96% to 93%.
